Abstract

The invention discloses a light-emitting diode and a manufacture method thereof. The light-emitting diode (LED) includes a first type semiconductor layer, a second type semiconductor layer, a current controlling structure, a first electrode, and a second electrode. The second type semiconductor layer is joined with the first type semiconductor layer. The current controlling structure is joined with the first type semiconductor layer, and the current controlling structure has at least one current-injecting zone therein. The first electrode is electrically coupled with the first type semiconductor layer through the current-injecting zone of the current controlling structure. The second electrode is electrically coupled with the second type semiconductor layer. The current-injecting zone can confine the contact area between the first type semiconductor layer and the first electrode, such that the current density that goes into the LED can be increased.

Description

technical field [0001] The content of the present invention relates to a light emitting diode and a manufacturing method thereof. Background technique [0002] In recent years, light-emitting diodes (light-emitting diodes; LEDs) have been commonly used in general household and commercial lighting applications. As a light source, light-emitting diodes have many advantages, including low energy consumption, long life, small size, and fast switching speed. Therefore, traditional lighting sources, such as incandescent lamps, have been gradually replaced by light-emitting diode light sources. In light-emitting diodes, when electrons and holes recombine across the semiconductor bandgap, the recombination energy is emitted in the form of photons and produces light. This recombination mechanism is the so-called radiative recombination. [0003] In an LED display using an LED array, in order to provide an appropriate brightness, eg, 500 nits (nit) to 3000 nits, the emitted energy o...
